5. ‘Help’ Crewmates (but not really)
Naturally, you want the crew members to eject as many of their own as possible. But in early game especially, your priority is to build up your own credibility. Covering for another player may therefore be a wise move. A phrase like “I think I saw pink complete a task, he is clear” will make you look trustworthy. With any luck, the player you covered for will remember that and be less inclined to vote you out later in the game.
Additionally, it can be wise to save an innocent player from elimination. If you create a tie between two Crewmates, the next round is still all about them. The Crewmates are wasting Meetings while you remain in the clear.
6. Crowd kill
When at least four players are standing on the same spot and one of them gets stabbed to death, it is very hard to determine who the killer was. You, as an Impostor, should make use of that.
So how do you get enough players in one place? As the numbers dwindle, it will be more and more difficult to find such a crowded area. But in early game you can, for example, sabotage the reactor. With some luck, many players will gather in the same spot to fix it. Pretend to be running to fix the reactor alongside them, wait a few seconds while everyone gets started, and then strike. Don’t forget to act surprised!
